To all fw/zom 'it may concern Be it knoivn that l, Cruonou L. HOWELL, acitizen of the United States of America, residing at Munger, in thecounty of Bay and .State of Michigan, have invented certain new anduseful Improvements in R0- tary Pumps, of ivhich the folloiving is aspecification, reference being had therein to the accompanying drawings.

rllhe invention relates to rotary pumps more particularlyT designed foruse in irrigation, and it is the object o-f the invention to obtain aconstruction Which is efficient, may be. constructed at small cost, andrequires little repair.

To this end the invention consists in the construction as hereinafterset forth.

ln the drawings: Figure l is a side elevation of the Wheel. Fig. 2 is anelevation at right angles to Fig. l. Fig. 3 is a cross section throughthe periphery of the Wheel showing the bucket construction.

A is a rotating shaft; B are spokes connecting the hub C with the rim D;E are buckets secured to the rim D and which are open at one side; and Fis a segmental plate which extends around a portion of the rim D andforms a cover plate for the open sides of the buckets. This plate ispreferably provided with flanges Gr and H for overlapping the outer andinner Walls of the buckets, the outer flange Gr being of greater depththan the inner flange H. The Wheel is preferably mounted in an inclinedposition as shown in Fig. 2 and the plate F is arranged adjacent to thedown-turned side and extends from the. bottom to near the top of theWheel.

l is a chute or trough, Which is adjacent to the upper end of the plateF and is arranged to receive the Water discharged from the buckets.

ln operation, motion is communicated to the shaft A from any suitablesource of poiver and the Wheel is driven in the dircction of the arroiv.The lovver portion of the ivheel, as for instance below the line J K, isbeneath the surface of the loiver ivater level, and consequently thebuckets E will be filled with liquid before passing into proximity tothe plate F. As the Wheel rotates these buckets will be carried aroundthe plate F, which latter will retain the greater portion of the Watertherein, particularly Where the Wheel is rotated at a relatively highvelocity. The overlapping flanges G and H, While out Specification ofLetters Patent.

l of contact with the buckets, are nevertheless sufficiently near toform a Water packing which will reduce the leakage to a small amount. Assoon as the buckets pass beyond the upper end of the plate F they arefree to discharge their contents laterally on to the chute l. and byreason of the inclined position of the Wheel the Water is rapidlydischarged, so that the buckets are completely emptied before passingbeyond the chute I.

The construction just described is one capable of being operated atrelatively high speed and the centrifugal force Will therefore lessenthe tendency to leakage around the inner flange H. On the other hand,there Will be an increased pressure of Water at the joint between theouter flange Gr and the buckets, I therefore constructed the outerlflange Gr of greater Width than the inner flange, as shown in Fig. 3.

that I claim as my invention is:

l. A rotary pump, comprising a rotating wheel, a series of relativelystationary buckets carried by the periphery of said Wheel and providedwith an open side for discharging laterally or sideWise in relation tosaid ivheel, a stationary segmental plate extending around a portion ofthe periphery of the wheel adjacent to said buckets and closing the openside thereof.

2. A rotary pump, comprising a rotating ivheel, a. series of relativelystationary buckets carried by said Wheel having open sides for lateraldischarge, a segmental stationary plate extending about a portion ofsaid ivheel adjacent to said buckets and closing the open sides thereof,and a flange at the edge of said plate overlapping the peripheral sideof said buckets and forming a Water packing.

3. A rotary pump, comprising a Wheel revoluble about an inclined axis, aseries of relatively stationary buckets carried by the peripheralportion of said Wheel, said buckets having open sides for lateraldischarge, a stationary segmental plate extending around a portion ofsaid Wheel adjacent t0 said buckets and closing the open sides thereof.flanges extending from opposite sides of said plate overlapping saidbuckets and forming a water packing, and a trough or discharge chute atthe upper termination of said plate for receiving the Water laterallydischarged from said buckets.

A rotary pump comprising a Wheel, a series of buckets attached to therim of said Wheel and having open sides for lateral discharge, each ofsaid buckets having peripheral segmental inner and outer Walls connectedby a return bend, a stationary segmental plate extending around aportion of said wheel adjacent to said buckets and closing the opensides thereof, flanges at opposite edges of said plates overlapping saidbuckets and forming a Water packing, and a trough 10 or discharge chuteat the termination of the upper end of said plate for receiving theWater successively discharged from said buckets.

In testimony whereof I affix my signature in presence of tivo witnesses.
